Check urine integrity with a Specimen Validity Test. From $0.95ea. 25/pk.
From $23.99 /box
This Specimen Validity Testing device is for checking urine integrity for six different abnormalities before performing a drug test. These abnormalities may be the result of substitute urine or contamination due to donor abuse. It tests for adulterated compounds, dilution and pH levels and more.
Check every sample with a Specimen Validity Test.
This device is used to identify abnormalities found in a person’s urine sample. These abnormalities may be the result of the donor adding a chemical to mask the outcome, dilution, and substitution. When used as directed, it establishes the integrity of human urine. The integrity has to be within standard parameters for the results of a drug test to work correctly. And remember, a donor trying to cheat their test will do what is needed to pass.
Sample adulterating by substitution or adding adulterants is a prevalent practice. Therefore, testing their sample is paramount when analyzing a sample for an abused substance — the test checks for Oxidants, Specific Gravity, pH, Glutaraldehyde, Nitrites, and Creatinine.
The strip is designed to evaluate a donor’s urine sample comprehensively. Abnormalities found will alert you immediately. Only when the donor’s specimen is balanced and has the correct pH level, specific gravity, and their creatinine levels are normal will they pass.
What is adulteration?
Adulteration is the tampering of a urine sample with the intent of altering the result. The use of adulterants can cause false effects in drug tests by interfering with the screening process and destroying the drugs present in the urine. Dilution may also be a tactic to produce false-negative results.
One of the best ways to check for adulteration is to determine specific urinary characteristics, as shown below:
- OX – Oxidants: Detects the presence of oxidants.
- S.G. – Specific Gravity: Checks for sample dilution.
- pH: Checks for the presence of acidic and alkaline adulterants.
- GLU – Glutaraldehyde: Checks for the presence of an exogenous aldehyde.
- NIT – Nitrites: Detects for commonly used commercial adulterants.
- CRE – Creatinine: Detects waste product called creatine present in human urine.
Directions for using the Specimen Validity Test before drug testing:
- Remove a strip from the canister. Dip the strip into the urine specimen and remove it immediately.
- Blot the strip gently on its side to remove excess urine.
Note: For consistent results, blot the strip every time a new one is used.
- Read the results at one (1) minute by comparing each pad with the color chart printed on the canister. DO NOT interpret after four (4) minutes.
- If the result indicates adulteration, refer to your supervisor or ask the donor to provide a fresh urine sample after a thirty (30) minute wait time.
This is an example of the color comparison chart and test strip (right) included in the package.
NIH recommends using an Adulteratant Test and suggests that it checks for pH and specific gravity for initial and confirmatory results.
How can a sample be adulterated?
Adulterants placed in urine will cause false negatives either by interfering with the screening process or by eradicating the presence of drugs. Examples of products that interfere with a drug test include bleach, vinegar, Visine, sodium bicarbonate, sodium nitrite, Drano, soft drinks, and hydrogen peroxide.
Why should I check a donor’s urine with a Specimen Validity Test?
Using a Specimen Validity strip or adulterant check, as it’s sometimes called, is the most effective way to monitor urine integrity. We cannot express how important checking every sample is before urine analysis. If you don’t, they win and pass the test. Proficient collectors/administrators always use Specimen Tests to beat the cheaters and validate the sample is suitable for the drug test kit.
